3M™ Saturated Glass Cloth Electrical Tape 90
Specifications
3M™ Saturated Glass Cloth Electrical Tape 90
is a saturated glass cloth electrical
tape with a rubber thermosetting adhesive. The tape shall be white and 7.5 mils (0.19
mm) thick. This tape shall be coated on one side with pressure-sensitive adhesive,
which shall not require heat, moisture or other preparation prior to or subsequent to
application. The adhesive coating shall be smooth and uniform and be free of lumps
and bare spots. There shall be no separator between adjacent layers of the roll. 3M
Tape 90 shall perform at a temperature of 310°F (155°C) without loss of physical or
electrical properties.
To achieve maximum solvent resistance and holding performance, we suggest
thermosetting the tape at one of the following cycles:
1 hour @ 150°C (300°F)
2 hours @ 135°C (275°F)
3 hours @ 120°C (250°F)
Shelf Life & Storage
